Check when starting if the fuel pump runs. If it does not, check the wiring. If you are sure with the relay and its terminals, it may be the car's computer module that may be bad. If the fuel pump runs during start, check if fuel runs to the engine after the fuel filter. If it is a new fuel filter, check if the fitting or connections are correct. If there is fuel after the fuel filter, it may be the injectors since fuel goes to the engine. Also related to the fuel being injected to the combustion chamber is the MAP sensor which measures the air in the intake and tells the engine how much fuel is needed. Check for the intake from the air filter for holes or tears. Check for loose vacuum hoses.

Sounds like a turn signal return spring and a rack pre-load spring. Go to a dealer and get a copy of the steering column and ask questions.

replace the ignition module,they are bad to do this on these years.

You must remove the fuel tank in order to replace the fuel pump. Drain the tank of as much fuel as possible with a hand pump. Disconnect the positive + battery cable. Disconnect the fuel lines and the electrical connections. Remove the fuel tank, and then remove the old pump. Clean off any old gasket and then reinstall the new pump. Reinstall the tank and then replace the fuel filter. A partially clogged fuel filter will cause a pump to fail prematurely.

you do not need to remove the lens assembly , only the bulb is replaced, you may need to loosen the battery if its in the way. if i remember correctly there is a black ring just a quarter turn then bulb pulls out. if no ring its just a quarter turn with the bulb and it out

Removal & Installation When replacing a serpentine belt, insert a 1/2in. breaker bar into the slot provided on the self-adjusting belt tensioner and pry up enough to slip the belt out from under the pulley. During installation, DO NOT allow the tensioner to "snap" back. Be sure to release the tensioner pressure slowly onto the belt.

1. If you are working near a battery, disconnect the negative battery cable. This is also advisable in order to prevent personal injury should someone try to start the engine while your hands are near the radiator fan or on a drive belt.
   
2. Loosen the mounting and adjusting bolts on the component whose belt is going to be removed.
   
3. Pivot the component inward toward the engine and slip the belt off the component's pulley.
   
4. Remove the belt from the crankshaft pulley, then remove the belt from the vehicle.
   

To install:

1. Position the belt to the engine and over the pulleys.
   
2. Properly adjust the belt by pivoting the component outward until the proper tension is achieved, then tighten the mounting and adjusting bolts.
   
3. Reconnect the negative battery cable.
   
4. 
   

if it is a slow crank try the starter

Your best diagram is the starter itself...make notes on where wires are attached and what you removed from where. Always remove the positive cable from battery before you begin and never allow wires on one starter terminal to touch ones from adjacent terminal when you replace them.
Remember...your starter turns the engine so it can start...it does not start your engine. Always have your battery charged and load tested to avoid changing the starter because the battery is bad.

u talkin 1940-dont think library even has that-try antique or classic magazines

Check your ignition switch - not the cylinder but the switch located under the dash on the steering column. You should hear an eletric click when you turn the key.

Try replaceing the ignition module sometimes these short out. I have a 89 BPA and two of my cylinders weren't running because of this..

Same here. What I do is lock all doors using the button on the driver's door before opening the door, then open the driver's door and lock it manually. That seems to keep it disarmed. I believe it has to be the driver's door for this to work, but I don't know for sure.

You may have bad head gaskets,if it is wet and slick it is antifreez.

CHECK ALL THE BULBS ON THE LEFT SIDE BECAUSE THE FUSE WOULD CAUSE BOTH SIGNALS TO NOT WORK.IT IS ALSO POSSIBLE THE TURN SIGNAL SWITCH IS BAD.

I'd make sure that a plastic bag or something hasn't been sucked up into the recirc intake, usually under passenger side dash.

Most likely gas line has rusted thru where it is clamped to the bottom of floorboard, or the fuel filter has rusted thru.
